Abstract
A method uses a firmware interface setup program for a selected compute node (“node”) to cause a firmware interface to enable a trusted platform module (TPM) on the selected node to receive a physical presence (PP) signal. The selected node is selected from a plurality of nodes within a multi-node chassis, wherein each node includes a firmware interface and a TPM. A device within the multi-node chassis is manually actuated to transmit a PP signal to each of the plurality of nodes, such that each node receives the PP signal. The PP signal is asserted to the TPM of the selected node in response to both enabling the TPM of the selected node to be able to receive the PP signal and receiving the PP signal. Still further, the method allows modification of a security setting of the selected node in response to the TPM receiving the PP signal.
